Abstract : It is considered likely that meteorological rocket which would have the brief capability of a meteorological satellite will soon be needed. Such a vehicle could be used to test out new ideas and equipment for meteorological satellites and to provide a quick satellite's eye view of a questionable weather area. It will be necessary for meteorological rockets to contain some type of attitude control. This report describes the factors involved in attitude control and develops a theoretical solution. Various known values are used with the formulas proposed to demonstrate the feasibility of the solution. It is concluded that the problem could be solved by applying impulsive torquing to bring the longitudinal axis of the rocket into correct alignment to produce the desired attitude. The torque could be applied by a cold propellant discharged by a bang-bang servo mechanism.
